Jobs, specifially those affecting my age group at the moment. You can't tell an entire generation to go to college, then tell them "well too bad, economy sucks and now there's no jobs for you to pay back your debt!" When all the jobs college kids would've had are given to others, it becomes harder and harder for me to find decent paying work. You go to college so you can avoid having to take a job at McDonald's not so you can get one at McDonald's.
The wage gap in general is a subject I wish more would do about, but hey- they get paid 6 figures with tax dollars alongside all the other money they have...
